# Red Hat Enterprise Linux (RHEL) Images

<code class="expression">space.vars.ionos\_cloud</code> is a certified partner of Red Hat and is entitled to offer and operate Red Hat Enterprise Linux (RHEL) within the <code class="expression">space.vars.ionos\_cloud</code> public cloud.

## Compatible versions

Currently, the entitlement is valid for RHEL 8 and RHEL 9 public images that <code class="expression">space.vars.ionos\_cloud</code> provides.

## Red Hat subscription

Currently, <code class="expression">space.vars.ionos\_cloud</code> does not provide any Bring-Your-Own-Subscription (BYOS) option for subscription-based operating systems like Red Hat Enterprise Linux. You still need an <code class="expression">space.vars.ionos\_cloud</code> subscription to use your images. <code class="expression">space.vars.ionos\_cloud</code> will charge you each time a [<mark style="color:blue;">Virtual Machine (VM)</mark>](https://docs.ionos.com/cloud/support/general-information/glossary-of-terms#virtual-machine-vm) boots from the private RHEL image. For more information about the charges, see [<mark style="color:blue;">FAQ</mark>](/cloud/backup-and-storage/images-snapshots/images-snapshots-faq.md#does-ionos-cloud-support-microsoft-sql-server-image).

Please ensure not to subscribe to or unsubscribe from sources of third-party subscription services to avoid duplicate charges for your Red Hat [<mark style="color:blue;">VM</mark>](https://docs.ionos.com/cloud/support/general-information/glossary-of-terms#vm) deployment. The subscription fee also includes access to the <code class="expression">space.vars.ionos\_cloud</code> Red Hat Update Infrastructure (RHUI) instance.

## IONOS CLOUD Red Hat Update Infrastructure (RHUI)

<code class="expression">space.vars.ionos\_cloud</code> operates its own instance of a Red Hat Update Infrastructure (RHUI). It is available by all public <code class="expression">space.vars.ionos\_cloud</code> IP addresses. <code class="expression">space.vars.ionos\_cloud</code> public RHEL images are preconfigured to access the <code class="expression">space.vars.ionos\_cloud</code> RHUI setup if the VM has access to the internet.

With the entitlement, RHUI enables <code class="expression">space.vars.ionos\_cloud</code> to provide the following services to end-users with an RHEL deployment:

* Mirror repositories hosted by Red Hat.
* Provide repositories with custom content supplied by <code class="expression">space.vars.ionos\_cloud</code>.
* Publish content to VMs running RHEL workloads.

## Select an RHEL image

An RHEL image supplied by <code class="expression">space.vars.ionos\_cloud</code> can be selected and configured like any other Linux-based public image. You can define the root password and specify SSH keys during provisioning. For more information about how to use RHEL images for your Block Storage, see [<mark style="color:blue;">Set Up a Block Storage</mark>](/cloud/backup-and-storage/block-storage/how-tos/set-up-block-storage.md).

## Access internet

You can access the internet using one of the following options when the VM contains a [<mark style="color:blue;">network interface</mark>](/cloud/network-services/vdc-networking/lan/how-tos/configure-private-lan.md):

* that is connected to a public LAN. The network interface has a public IP address. If you have a firewall configured, you may need to allow access to the subscription endpoint and service port.
* that is connected to a private LAN which is capable of accessing a [<mark style="color:blue;">Managed NAT Gateway</mark>](/cloud/network-services/nat-gateway.md). The NAT Gateway must be configured to access the public internet endpoint of the subscription service.
* that is connected to a private LAN containing other VMs that could act as a proxy to the public internet. Connectivity must be configured manually via the routing settings within the VM.

## Access information for the IONOS CLOUD RHUI service
